AirDrop doesn’t exist between a Windows PC and an iPhone, and I got tired of emailing myself links. airplop is the fix: a small Flask server running in WSL2 that pushes whatever you paste to every connected phone in real time over Server-Sent Events. The phone just opens a Safari page — no app, no account.

The interesting problems were all networking, not web dev: getting traffic from a phone through Windows into a WSL2 VM (a one-time PowerShell script opens the firewall and installs a logon task so the port-forwarding survives reboots), and keeping the phone’s bookmark stable when the LAN IP changes — solved by advertising airplop.local over mDNS with zeroconf, plus a QR code on the sender page for first-time pairing.
